DESCRIZIONE
A radar system (1) comprising: a transmitting antenna comprising a plurality of linear arrays (tl-t4) of transmitting antenna elements (20) arranged on a generatrix of a truncated cone or on a cylindrical surface; a signal generator block (2) operatively connected to the transmitting antenna and adapted to feed the transmitting antenna; a receiving antenna comprising a plurality of groups (g1-g4) of linear arrays (r11-r1n,..., r41-r4n) of receiving antenna elements (10) arranged on the generatrix of the truncated cone or on the cylindrical surface, in which each group (gl-g4) of linear arrays of receiving antenna elements is circumferentially interposed between a first and a second linear array of transmitting antenna elements; a signal processor (drx, 4) operatively connected to the receiving antenna. The signal generator block (DRX, 4) is adapted and configured to feed the transmitting antenna so that the first and the second linear arrays of transmitting antenna elements emit a first and a second electromagnetic radiation, respectively, at a first and a second frequencies different from each other.
